Copper And Stainless Steel Compatibility

Stainless steel chemical compatibility chart.

Copper and stainless steel compatibility.

Based on their material compatibility with the substrates. Galvanic corrosion some times called dissimilar metal corrosion is the process by which the materials in contact with each other oxidizes or corrodes. Copper bronze a d e a b a e stainless steel 300 series a d e a a a e. Stainless steel in contact with other metallic materials diamant building bd.

Stainless can be susceptible to corrosion when chlorides are elevated. When dissimilar metals contact in the presence of an electrolyte a galvanic action occurs which causes one of the metals to corrode at a much faster than normal rate while the other corrodes more slowly if at all. This is because stainless steel and copper are actually dissimilar metals. Dissimilar metals are not.

An effect that may occur is a corrosion known as galvanic corrosion which may happen with the contact of two dissimilar metals in the presence of. Bituminous or zinc chromate primers can be used between copper and aluminum. When stainless steel is. Galvanic and corrosion compatibility dissimilar metal corrosion guide quality engineering and design requires an understanding of material compatibility.

The information in this chart has been supplied by reputable sources and is to be used only as a guide in selecting equipment for appropriate chemical compatibility. Unfortunately ro water can be a nebulous term since ro is a reductive membrane separation process it will reduce the influent contaminants by whatever the rated reduction rate is of the membrane s at the operating tmp and flux rate. Fasteners that are compatible with preservative treated lumber are stainless steel fasteners or hot dip galvanized nails manufactured. 316l stainless steel chemical compatibility chart ver 10 jan 2020 industrials key to general chemical resistance all data based on 72 22 c unless noted explanation of footnotes 1 satisfactory to 120 f 48 c a excellent no effect c fair moderate effect not recommended.

Similar metals are compatible. Iron and steel are generally not a problem unless their mass is similar or smaller than that of the copper. When two dissimilar metals are directly connected together the lesser of the two metals experience galvanic corrosion which on a molecular level means that one metal readily gives up its electrons and one metal holds onto their electrons. Check the chemical compatibility of stainless steel with various chemicals solvents alcohols and other products.
